Do It Best 605900 Calcium Lime Rust Remover 128 Oz

Product Description

The DO IT BEST 605900 is a heavy-duty liquid cleaner formulated to dissolve calcium deposits, lime scale, and rust stains from a wide range of surfaces. It works by chemically breaking down mineral buildup and oxidized iron deposits on contact, making it effective for both light maintenance cleaning and stubborn hard water accumulation. Recognized under the EPA Safer Choice program, the formula is designed to be safer for human health and the environment without sacrificing cleaning strength. This product is appropriate for use by plumbers, HVAC service techs, pool professionals, and facility maintenance personnel who routinely deal with mineral-fouled fixtures and equipment.

The 605900 is suited for residential and light commercial applications where calcium, lime, and rust deposits are a recurring problem. Typical use cases include descaling shower heads, toilet bowls, faucets, coffee equipment, tile and glass surfaces, and exterior siding. It is particularly useful for plumbing service calls involving hard water damage to fixtures, as well as HVAC maintenance on condensate pans and evaporator coil drain components where mineral scaling is common. The 128-ounce container size supports multiple service visits or thorough whole-facility cleanouts without requiring frequent restocking.
